the use of which colors of all tints can be produced.

Oil, essence and varnish paints are now i to be found in the trade, but are expensive and health injurious on account of their zinc or lead content. On the other hand, size colors are known which are cheap but are neither washable nor durable.

The purpose of this invention is to provide a novel product whereby the aforesaid drawbacks are avoided, .i. e., to produce a novel paint which is cheap and not liable to injure the health of the workman while possessing all the properties of theexpensive paints known up to present time. In other words, this paint may be washed, brushed and used in-doors as well as outof-doors.

The process for making this product is as follows:

Wax is dissolved under heating in a suitable essence, preferably in spirits of turpen tine and a solution of soap in hot water is added thereto. A solution of glue in hot water is then added to the mixture, after which linseed oil is poured into the hot liquid compound obtained.

To this mixture is then added albumin warmed by means of hot water.

The mixture is thoroughly stirred and finally metallic or mineral whiting is added thereto, the choice between the kind of whiting to be used depending upon the special properties required. By using mineral whiting (comprising ground chalk free from impurities) in combination with the hereinafter specified materials, the paint obtained will be cheap, hygienic, and firm. If the paint desired must have more consistency, whiting (such as a mixture of zinc sulphide with barium sulphide) may be substitutedpartly or wholly for the mineral whiting but the 1paint will lose its hygienic 1 be more expensive.

The Quantities of materials to be used for PI'OflHCIIIg 100 pounds of paint are the following:

It w1ll be understood that the invention cons1s ts in compounding together the above materials in suitableproportions, those-indicated having been found to give very good results.

What I claim is 1. A paint paste comprising a mixture of soap, glue, spirits of turpentlne, wax, linseed o1l, albumin, water and whiting, substantially in the proportion'of two parts of soap, one and two-thirds parts glue, four parts spirits of turpentine, one and twothirds parts wax, four parts linseed oil, tfiree and one-third p-arts' albumin, thirtyt ree and one-third parts water, and fifty parts whiting, by welght.
